2003 PONTIAC BONNEVILLE maintenance

Part A: Scheduled Maintenance
Services
In this part are scheduled maintenance services which
are to be performed at the mileage intervals specified.
Using Your Maintenance Schedule
We at General Motors want to keep your vehicle in good
working condition. But we don’t know exactly how
you’ll drive it. You may drive short distances only a few
times a week. Or you may drive long distances all
the time in very hot, dusty weather. You may use your
vehicle in making deliveries. Or you may drive it to
work, to do errands or in many other ways.
Because of the different ways people use their vehicles,
maintenance needs may vary. You may need more
frequent checks and replacements. So please read the
following and note how you drive.
If you have
questions on how to keep your vehicle in good condition,
see your dealer. This part tells you the
maintenance services you should
have done and when you should schedule them.
When you go to your dealer for your service needs,
you’ll know that GM-trained and supported service
people will perform the work using genuine GM parts.
The proper fluids and lubricants to use are listed in
Part
D. Make sure whoever services your vehicle uses
these.
All parts should be replaced and all necessary
repairs done before you or anyone else drives the
vehicle.
These schedules are for vehicles that:
carry passengers and cargo within recommended
limits. You will find these on your vehicle’s
Tire-Loading Information label. See
Loading Your
Vehicle on page 4-34.

Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:
Follow the Short Trip/City Scheduled Maintenance
if any
one of these conditions is true for your vehicle:
0 Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
0 Most trips include extensive idling (such as frequent

0 If the vehicle is used for delivery service, police,
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.

Long Trip/Highway Definition
Follow this scheduled maintenance only if none of the
conditions from the Short Trip/City Scheduled

Do not use this schedule if the
vehicle
is used for trailer towing, driven in a dusty area
or used
off paved roads. Use the Short Trip/City
schedule for these conditions
Driving a vehicle with a fully warmed engine under
highway conditions will cause engine oil to break down
slower.

Change (or every 12 months, whichever occurs
first). Tire Rotation.
Every 30,000 Miles (50 000 km): Supercharger Oil

Be sure to follow the complete scheduled maintenance
on the following pages.
Short Trip/City Scheduled

The services shown in this schedule up to 100,000 miles
(1 66
000 km) should be repeated after 100,000 miles
(166
000 km) at the same intervals for the life of
this vehicle. The services shown at 150,000 miles

Footnotes
t The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle
's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
*If your vehicle has the GM Oil Life SystemTM,
a
computer system lets you know when to change the oil
and filter. This is based on engine revolutions and
engine temperature and not on mileage. Based
on driving conditions, the mileage at which an oil change
will be indicated can vary considerably. For the oii life
system to work properly, you must reset the system
every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. An ENGINE
OIL CHANGE SOON message
will come on. Change your oil as soon as possible
within the next two times you stop for fuel. It is possible
that, if you are driving under the best conditions, the
oil life system may not indicate that an oil change
is necessary for over a year. However, your engine oil
and filter must be changed at least once a year and
at this time the system must be reset. It is also
important to check your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles
(5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. See Engine Oil on
page
5-15 for information on resetting the system.
@ Whenever the tires are rotated, the Check Tire
Pressure §ystem must be reset.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-23.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield.
Also see
“Windshield Wiper and Wiper Blades” under Cleaning
the Outside
of Your Vehicle on page 5-85.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth, During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page
6-24.
Automatic Transaxle Check
Check the transaxle fluid level; add if needed. See
Automatic Transaxle Fluid on page 5-23. A fluid loss
may indicate a problem. Check the system and repair if
needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part
D.
Lubricate all hinges and latches, including those for the
hood, rear compartment, glove box door, console
door and any folding seat hardware. Part D tells you
what to use. More frequent lubrication may be required
when exposed to a corrosive environment.
6-1 9

Part C: Periodic Maintenance
Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,
each spring and fall).
You should let your dealer’s
service department or other qualified service center dc
these jobs. Make sure any necessary repairs are
completed at once.
Proper procedures to perform these services may be
found in a service manual. See
Service Publications
Ordering Information on page
7-9.
Steering, Suspension and Front
Drive Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals
if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams,
holes, loose connections or other conditions which
could cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See
Engine Exhaust
on page
2-36.
Fuel System Inspection
Inspect the complete fuel system for damage or leaks.

Part E: Maintenance Record
After the scheduled services are performed, record the date, odometer reading and who performed the service and
any additional information from “Owner Checks and Services” or “Periodic Maintenance” on the following record
pages. Also, you should retain all maintenance receipts.
